ON Semiconductor MAX809SN490T1G Voltage Supervisor

The MAX809SN490T1G is a highly precise voltage supervisor component designed by ON Semiconductor, a leading manufacturer in the electronics industry. This microprocessor (μP) supervisory circuit is engineered to monitor the power supplies in μP and digital systems, providing a significant function in the management of system integrity.

Key Features:

• Voltage Threshold: The device features a preset voltage threshold of 4.90V, which is ideal for 5V-powered applications. When the monitored voltage falls below this threshold, the MAX809SN490T1G actively asserts a reset signal to safeguard the system.
• Reset Timeout: It comes with a 140 ms minimum reset timeout duration, ensuring that the system has sufficient time to stabilize before the reset condition is deasserted.
• Low Power Consumption: The MAX809SN490T1G is optimized for low power consumption, making it suitable for power-sensitive applications.
• Output Type: The reset output of the device is active-low, open-drain. This configuration allows for a simple interface with other logic components and provides the ability to wire-OR the output with other open-drain or open-collector outputs.
• Temperature Range: The device operates effectively over a wide temperature range, from -40°C to +125°C, accommodating a variety of operating environments and conditions.
• Package: It is available in a compact SOT-23 package, making it suitable for space-constrained applications.
